中文摘要：
根据锈蚀钢筋混凝土压弯构件的反复加载试验结果,分析了反复荷载下钢筋锈蚀对锈蚀构件刚度退化的影响规律。研究表明：较小的钢筋锈蚀率对试件刚度退化影响不大,当钢筋锈蚀率增大到3%左右时锈蚀试件的刚度退化速度开始加快。
英文摘要：
Through the cyclic test of reinforced concrete column for axial load and moment under different axial compression ratio,the effect of steel corrosion rate on stiffness deterioration is analysed.The results show that as corrosion rate is low,it is of little influence on stiffness deterioration.However,stiffness deterioration began to accelerate when corrosion rate increases to 3%.
